Newbie here Nexstar 6se - whats the best eyepieces to buy
« on: December 24, 2017, 01:56:09 PM »
Newbie just purchased nexstar 6se I simply used for the first time last night only with stock parts wondering what is the best eyepieces I should invest into.  Im looking for hints or others have used on same range nexstar 6se and how they enjoyed them.  I am upgrading the Diagonal toHigh Stage 2" SCT Quartz Dielectric Diagonal - D2QSCT looks like best buy for what you receive any suggestions will be appreciated.  The eyepieces Ive looked at will be the Explore Scientific 20 mm - 68?? Argon-Purged Waterproof 1.25" Eyepiece - EPWP6820-01,Explore Scientific 6.7 mm - 82?? Argon-Purged Waterproof 1.25" Eyepiece - EPWP8267-01,Explore Scientific 11 Y - 82?? Argon Purged Waterproof 1.25" Eyepiece - EPWP8211-0,Baader 17.5mm Morpheus 76?? Eyepiece - 1.25"/2" - MORPH-17,Baader 6.5mm Morpheus 76?? Eyepiece - 1.25"/2" - MORPH-6,Baader 9mm Morpheus 76?? Eyepiece - 1.25"/2" - MORPH-9,Baader 14mm Morpheus 76?? Eyepiece - 1.25"/2" - MORPH-14.  Those are the ones Ive been studying but Searching for counsel on witch ones would give me the best views on my new range

If you've got enough money, go for baader 8-24mm zoom EP.  It will cost you, but it will function as at least 3-4 EPs.  It is a quality build and can be used for 1.25 inch or two inch.

I concur with the Baader zoom recommendation. A range of 8-24 mm is perfect for a 6 inch SCT. If you're willing to wait, you can get one Cloudynights classified board for about $200-250.

You've really got your ep's covered quite well. Add a widefield if you like but that very nice scope is never going to be a widefield instrument no matter what you hang on it. If you use a zoom instead of what you have, you're going to lose FOV in the critical midrange.
Just go observe. That's what it's all about.

The highest power I have been able to consistently use with my 8se has been 10mm. Seeing where I live rarely lets me go any higher. My 2 most used eyepieces are an explore scientific 82* 14mm and an explore scientific 82* 18mm 2" for a wider FOV. I also use a Meade series 5000 2" 28 mm for an even wider FOV. I have not used the Badder zoom but it may be a good choice until you figure out what you like to observe. I really enjoy having a wider FOV when looking at clusters. Zoom eyepieces tend to give restricted FOV at lower powers. I'm not sure if that is the case with the Badder zoom but you will get a very wide range of powers in one eyepiece.

I have the 6SE and the good thing about it is it's easy on eyepieces. Even the plossl's work well in the longer Focal lengths. In the shorter focal lengths eye relief gets tight. The Explore Scientific 6.7 mm - 82º would be a good choice for high power. That's probably close to the usable limit on most nights. I have The ES16mm and I really like it for open clusters and DSO. You'll want something in between the 2. I just use the 16 with a 2x barlow or a 10mm Plossl but if you want to spend money you could get the ES 82° 8.8mm or the Baader 9mm. I would suggest doing some observing before you spend too much. As I said the plossl eyepieces work quite well with the scope. I also have the 6.3 focal reducer and leave that in most of the time. It will give you a wider fov with all of your eyepieces and it comes in handy if you want to do any astrophotography or EAA. Get the Meade, it's the same as the Celestron and only $69.

Welcome to CN Brian, I hope you are enjoying your fine scope.

I am a SCT/Mak observer with similar focal lengths and I observe a bit of everything. Moon and planets from my heavily light polluted SoCal home and DSOs when I can get out to the desert and dark skies. In my experience you don't really need a lot of EP to enjoy the sky with an SCT. A decent 32mm and focal reducer are good for DSO views, the 8x24 zoom can cover nearly everything else. I don't see much advantage in going with 2" EP on this scope. They are big $$ and you are field limited by the SCT design so you won't get the full advantage you might see with a 12" Dob under dark skies. For sweeping wide field views I prefer a decent set of binocs which compliment the SCT design very nicely. Few scopes can match the 7 degree field of view and breathtaking sweeps of the milky way that you can get rather easily with a nice $200 pair of binoculars.

You have my recommendations and others will surely disagree. Ask 10 backyard astronomers and you will get 12 different opinions based on our own personal experience. For now, use what you have and really take in the moon and planets that are well placed for viewing tonight. Learn how to use your tool well.

I'm not going too deep into the which is the better eyepiece discussion......There is just too much to discuss, and I have not tried them all. I would, however, offer the following:

1. Slow down. You do not need to buy a bunch of eyepeices all at once.

2. Think it out. Some general rules of eyepieces are that you want something that will give you the widest field possible, something that will give you about 150 power, and something about two thirds the way in between those two. Then add a 2x Barlow. WIth your 1500 mm scope, this would suggest a 30 mm, a 24 mm, and a 10 mm. This gives you the range of 300 power (barlowed 10--usable only on the steadiest of nights, and pushing your C6 to its limits), 150 (10) for typical nights high power viewing, 125 (barlowed 24), 100 (barlowed 30), 63 (24--this will be your most widely used except on solar system), and 50 (30). Actually, for my money, I would skip the barlow. I just find that three good eyepieces usually do the trick.

3. Yes, someday you will have a half dozen or (many) more eyepieces. But you can get by pretty darn well with three good ones. I only have more than three because I have lots of different tubes. But, really, on any given telescope, I use maybe three.

4. Get the highest quality and widest FOV you can afford.

5. Two inch diagonal on that little bugger? I just set mine up for the first time last night. I did not even know it could accept a two inch diagonal. Of course, I bought mine for outreach, always in a light polluted city setting. So, I will only get to look at solar system and an occasional deep sky object.

6. there is a lot to say for zoom eyepieces. But FOV is really lacking. You would do better, I think, with separate oculars.

Just my opinion.

My understanding is that there is NO BENEFIT to going 2" on a 6SE. The optical train can't take advantage of a 2" focuser.  I don't have one but I read that over and over.

LOTS of good choices on eyepieces.

Low power/wide view - Get a 32 mm 1.25" Plossl eyepiece to get your widest view for that scope.Zoom - I am very partial to the Baader Hyperion 8-24 zoom for all of my scopes.  The Celestron 8-24, which I also have, is a great value for the price but not as good as the Baader.  I have both of these
http://agenaastro.co...lanetarium.htmlSingle FL - If you prefer single focal length eyepieces I would recommend the Explore Scientific 68 degree and 82 degree line or the Meade 5000 Ultra Wide Angle (82 degrees). I have these.

Congratulations on the new scope. Love mine. I won't recommend any brand because I don't have the experience with the different brands. I'm not a fan of zooms because of the narrow fov at higher magnifications and I seldom use my Barlow. I do like my 8mm in my scope and it gives great views of the moon and Jupiter at 188x, though I plan on getting an 8 or 9 mm with a wider fov because the plossel is just too hard for me to use. I'd recommend a 32mm plossel for wider fov, an 8 or 9mm with a 62 or 68 fov and something in the range in between, 12 to 18 mm. At least that's my plan for my Nexstar 6. I'll probably get a 6mm eventually for a bit more power on the planets. Just imho.

EYEPIECESSelecting an eyepiece - Orion telescope
This is a very general discussion of eyepieces and why there are a variety of designs
https://www.youtube....h?v=m7u9Q5hV7ycEyepiece Designs - This is the one I turn to when I am trying to understand or explain the
differences between the various designs. There are many different designs, Many are named
for their original designer, such as Huyghens, Ramsden, Kellner, Plossl, Konig, Erfle, Branden and Nagler.

When selecting eyepieces the things to consider are; price, eye relief, AFOV
Here is what I have learned. Open a spreadsheet and do the math on eyepieces focal length, aperture, and telescope focal length (include barlow's at the top) eyepieces in the 1st column.
Here is my example:
EP mm 1x    2x     2.5x
32.0   20    41    51
20.0   33    65    81
14.5   45    90    112
12.5   52   104   130
9.0    72   144    181
6.0    108  217    271

If you want a simple way to see what any eyepiece will do in your scope go to the Astronomics website. Choose an eyepiece. When you open the page for that eyepiece there is a tab for formulas. All you do is enter the focal length of your telescope and it will tell you what power and fov it will produce in your scope.

It is good to get to know the forumula for magnification, especially if you are comparing between different scopes.Telescope FL/eyepiece FL = Magnification expressed as a power

1200 mm/6 mm = 200XApparent Field of view of eyepiece/magnification = true FOV

Assuming a plossl eyepiece, 52 degree AFOV, in the above example

52 degree AFOV/200X = .115 degree FOV

As I have 3 scopes of very different FL I run these numbers all the time for my observation reports.
